The report provides a summary of works undertaken during the period 2017&ndash

This report presents the proposed future directions for long-term pavement performance (LTPP) studies in Australasia. The proposed way forward is based on the results of a 2017 survey directed to the LTPP Project Steering Group (PSG) and Assets Task…

The aim of this project was to clarify the effectiveness of pavement maintenance (preservation) activities, in the form of periodic maintenance and rehabilitation, on pavement condition and distress (roughness, rutting and cracking) deterioration…

The report provides a summary of works undertaken during the period 2016–17 for the Austroads project AT1064 – Long-term pavement performance (LTPP).

Austroads has funded the long-term pavement performance study since late 1994. The project monitors…

Part 4B of the Austroads Guide to Pavement Technology provides a recommended approach to the design and characterisation of asphalt mixes in Australia and New Zealand. However, the approach to asphalt mix design and performance characterisation…

The Austroads asphalt pavement design process set out in Guide to Pavement Technology – Part 2: Pavement Structural Design (Austroads 2008) utilises a mechanistic procedure to predict the allowable traffic repetitions until asphalt fatigue occurs.…

Part 6 of the Guide to Pavement Technology addresses unsealed pavements including operational demands of unsealed road surfaces, pavement configurations, floodways, cuts, fills and mine haul roads, the identification of suitable pavement materials…

A study of published information regarding the design and development of stone mastic asphalt (SMA) was undertaken. The main focus was upon obtaining information that had resulted in successful SMA mixes. In most instances the design of SMA had used…

This test was conducted to determine the relationship between wheel tracking characteristics found in a laboratory and rutting in real-world scenarios. A road trial was established in Brisbane at the Mount Coot-tha quarry. The site was chosen as it…

This document provides a guide to preparing samples for asphalt mix design to conform to Austroads design processes. It covers splitting of the raw components as well as compacting cylindrical and prismatic samples. The loose asphalt conditioning…
